 python - Number/Version Paddings in Maya - Stack Overflow
don't know why I've never really had to do this before heh. Watch out for the backticks. The python bit really wants the ' and not the `, but then the mel bit really wants the `. sigh.
Also hilarious that you have to use a python function for this.

$padding = 3;
$num = 5;
string $pad = `python ("'%0"+$padding+"d' % "+$num)`;
// Results is: 005

deleting uv sets maya

 Maya 2020 UV Sets infuriating - need help : Maya (reddit.com)

sometimes you need to kill uv maps, you have to move the one you want to delete so it isn't at the top of the list - it can only be moved if you use the UV Toolkit mode - right at the bottom of the tabs there'll be a UV Sets rollout that lets you do so & delete the offending sets. VERY SHITTY.

python way of making the bones based on cvs

changing the orientation on the joints should be easy enough look to the script for

this line

cmds.joint(currentJoint,e=True,zso=True,oj="xyz")

change the oj=“xyz” to the orientation you need… more than likely you are looking for “xzy”.

The import maya.cmds as cmds line imports the MEL script commands to python. There are some differences, but there is a lot of good documentation, and a number of references out there.

as for reorienting the joints. change the following line i=1 in the last block to i=0 that will start the orientation at the base joint instead of the second joint. A lot of times I leave the base joint aligned to world for my own uses.

 import maya.cmds as cmds

# array of selected objects

sel = cmds.ls( selection=True )

# name of the curve to convert

lastSelect = int(len(sel)) -1

curveSel = sel[lastSelect]

# print lastSelect

#print curveSel

#find the number of CVs (Degree + Spans)

numCVs = int(cmds.getAttr (curveSel+'.degree'))+ (cmds.getAttr (curveSel+'.spans'))

#print numCVs

# selection must be clear

cmds.select(clear=True)

#For each CV in the Curve create a joint.

i=0

while 1:

    if not ( i < numCVs ):

        break

    cvPosition = (cmds.getAttr (curveSel+'.cv['+(str(i))+']'))

    if (i == 0):

    cmds.joint(n=curveSel+'_jointRoot',p = cvPosition[0])

    if (i == (numCVs-1)):

    cmds.joint(n=curveSel+'_jointEnd', p = cvPosition[0])

    if(i>0)and(i != numCVs-1):

    cmds.joint(n=curveSel+'_joint_'+(str(i)),p = cvPosition[0])

    i+=1

 

# reorient the joints    

i=1

while 1:

if not (i < numCVs-1):

break

#find the name of the current Joint

currentJoint = (curveSel+'_joint_'+(str(i)))

cmds.joint(currentJoint,e=True,zso=True,oj="xyz")

i+=1

UVs for a ribbon/pipe

1) Use the Unitize function to separate each face in the mesh and have them squarely fill the 0-1 UV space. 2) Select the edges where you want your seam. 3) Convert the selection to UV's. 4) Invert the selection. 5) Use the Move and Sew function. 6) Go in the option box for Unfold and select Vertical as your unfold constraint (horizontal if your UV's are oriented that way. 7) Enjoy your nice UV's.

simple sticky lips

http://www.kimonmatara.com/maya-easy-sticky-lips/

To begin, create two curves that will follow the contours of the upper and lower lips respectively as your rigged geometry deforms. These will be your ‘driver’ curves. There are various ways of doing this; in the example below, I merely drew the curves using snapping, and then wrapped them onto the original rig geometry:

Next, create a dynamic ‘averaged curve’ between them. To do this, follow these steps:

1. Grab the curves’ shapes and graph them up in the Node Editor (or Hypershade, as you prefer).
   
2. Create an ‘avgCurves’ node (in the Node Editor, you can hit tab and start typing ‘avgCurve’; alternatively, you could just issue a ‘createNode avgCurves’ in the MEL command line)
3. Plug the ‘worldSpace’ output attribute of each curve shape into the inputCurve1 and inputCurve2 inputs of the avgCurve node:

4. Back in the Outliner, duplicate one of the curves. This will be your ‘sticky’ curve.
5. Add this curve’s shape to the Node Editor graph.
6. Plug the ‘outputCurve’ output of the avgCurves node into the ‘create’ input of the curve:

7. Select the avgCurves node and switch off ‘Automatic Weight’.

The resulting curve should fall right between the two lips, as thus:

Next, make a live, deforming copy of your rigged geometry. To do this, select your rigged geometry and issue ‘polyDuplicateAndConnect’ in the MEL command line. This will be your ‘sticky lips’ mesh. (This step is necessary to prevent dependency graph cycle problems.)
Now set the the averaged curve you created earlier as a wire deformer for this mesh. If in doubt as to how to do this, consult Maya’s documentation on the ‘wire’ deformer.
The wire deformer will have generated a ‘BaseWire’ curve. Select this curve’s shape in the Outliner and graph it in the Node Editor. Add the ‘avgCurve’ node you created originally to the graph.
Once again, plug the ‘outputCurve’ output of the avgCurve into the ‘create’ input of the BaseWire curve. We are doing this to cancel-out the wire deformer’s effects:

Paint-out the wire deformer’s influence to a narrow area along the inner lip edges:

Set ‘scale[0]’ on the wire deformer to 0.0, turn up the ‘dropoffDistance’ attribute, and overdrive ‘envelope’ to 2.0. Play with these settings until you get a good-looking result kicking in at the right range of motion.

You should now have something like the image below. If you turn up the wire dropoff, you’ll be able to zip-up the whole mouth, from the edges inwards.

• The effect is distance-based, so some modest keying will be required in animation.

render layers in maya 2018

Render layers in 2018

Use groups in collections, this way you can easily swap out geo without having to update stuff each time someone changes something.

If a sub object needs changing, it could be worth putting that in a sub group too.

Use shader overrides rather than material overrides.

more UV crap

last post is a bit redundant in the age of UV-editing mode of Maya 2018, but with heavy meshes, the uv editor is dog slow.

polyEditUV -u 1 -v0 -scaleU 1.2 -scaleV 1;

Also this.

zbrush displacement map transfer etc.

Zbrush is still a pain. But a useful pain.
The situation is : Say you have a hi-res piece of geometry. You'd like to use a retopo'd low-res geo as a base mesh for subdivision and displacement. Mudbox doesn't really cut the mustard for this. And Maya's transfer map results are even more useless. Here's what you do.

• Bring in your low-res UV'd geo to Zbrush. Turn it into a polytool so it sits in Zbrush's memory.
• Now import your hi-res geo. It should replace everything in the scene
• Go to the Subtool menu, select append and look for the polytool of the low-res geo you just created. Click it.
• Hide the hi-res geo for the time being. 
• In the Geometry menu, hit subdivide a bunch of times, to get enough hi-res detail. You probably don't need to go as high as the unoptimised hi-res geo.
• Go back to the Subtool menu, show the hi-res geo again.
• Click on the now-subdivided low-res geo and hit Project All. This is at the bottom of the Subtool menu.
• Now your subdivided low-res geo should have taken on the detail from your hi-res geo.
• Lower the subdivision level in the Geometry menu. Do the Project All again. Repeat for every lower level.

Now for the map generation bit

• Set your low-res geo subdivision level to it's lowest setting. OR to whichever level you want to use as your base in Maya/Houdini/whatever.
• In Z-Plugins, click Multimap Exporter and select the maps you'd like generating.
• Make sure Flip V is ticked ON.
• Make sure Smooth UVs is OFF.
• Subdiv level should be at 1 or whichever level you've chosen.
• For final map turn ON Adaptive.
• Turn on 32bit EXR.
• The rest is fine to leave as default. Scale should be 1. 
• Click Export maps.

SHOULD WORK. DON'T HAVE MULTIPLE UV TILES. DON'T HAVE UV's ON THE EDGE OF A TILE. ZBRUSH IS STUPID AND WILL MESS UP YOUR BAKING.

moving specific Mash points

How to manually move points in MASH, using the python node..
Bold bits are the important lines of code, where 7 and 16 are the point numbers (add a Points node to see numbers). I'd assume you could hide specific points here too?



import openMASH

#initialise the MASH network data
md = openMASH.MASHData(thisNode)

#this is how to get the frame number
frame = md.getFrame()
#and this gets the number of objects in the network
count = md.count()

#add the index to the Y position
#for i in range(count):
#    md.outPosition[i].y=i

md.outPosition[7].y+=2;
md.outPosition[16].z+=3;
md.outVisibility[12]=0;
md.outRotation[12].x=12;

#tell MASH to write the network data
md.setData()


The docs say you can change -

• outPosition
• outScale
• outRotation
• outId
• outVisibility

seem to use this a lot - set matte attr for arnold crap

string $selectedStuff[]=`ls -sl`;


int $sizeArray=size($selectedStuff);
for($i=0; $i<($sizeArray);$i++){
print $selectedStuff[$i];


setAttr ($selectedStuff[$i]+"Shape.aiMatte") 1;
//setAttr ($selectedStuff[$i]+".overrideLevelOfDetail") 1;
   
   
}
